Abstract
Abstract An improved kickover tool and well valve handling apparatus for placing a valve in or removing a valve from an offset side pocket in a well tubing and having a support body, a shifting tool pivotally supported from the support body with spring means yieldably urging the shifting tool into the side pocket by providing means for releasing the shifting force of the spring from the shifting tool after use whereby the shifting tool may become aligned in the well tubing for removal. The spring being a leaf spring with one end held under compression by shear means engageable by a valve handling support so as to be sheared when the valve handling support is pivoted relative to the shifting tool so that the shifting tool may become pivotally aligned in the tubing from the support body. Adjustable means for moving the valve handling support about a pivot from the shifting tool for engagement with the shearing means. A rotatable joint connected between the support body and the shifting tool secured by a shear pin to the shifting tool and sheared by movement of the shifting tool relative to the body for allowing greater lateral shifting movement of the shifting tool.
